A method for predicting and calculating the harmonics of no load voltage of salient rotor synchronous generator is derived in this paper. According this method, the amplitude of harmonics and voltage harmonic distortion can be calculated by the shape and size of field pole and the construction of the stator winding in the design stage. Thus, the design of the machine construction can be optimized to suppress the voltage harmonics and to improve the EMC (electromagnetic compatibility) of the machines.
